lol its not a myth- you guys keep referencing cervantes' but he supports this.
I have watched videos where he himself says to lower light, and do a dark harvest- or harvest before light comes on.
Marijuana man also supports lowering light to some degree.
And finally Arjan lowers lights with some of his indica varites....
Its not a myth its an option, and there is no reason to kill science... its like destroying evolution- so you believe in creationism its cool man, but lowering the light works for many. And I haven't heard much referencing to lowering yield.
What I have heard to do is to cut light to 10 or 8 depending on variety for weeks 6-8, then going week 9 for 12-14 depending on cockyness. This will trigger them to milk up great from 6-8, then amber up for 9. But thats just my opinion and what i have read and heard testimonial style.
No matter the fact, i dont think people should be told its not true. If anything the contrary- people should try it, and report it on the threads such as this one that talk about that.
I rep your behavior russ, for science let us know how it goes.
for science,
OB
